Servier Gets OK for Brain Tumor Drug
FDA has approved a Servier Pharmaceuticals NDA for Voranigo (vorasidenib), an isocitrate dehydrogenase-1 (IDH1) and isocitrate dehydrogenase-2 (IDH2) inhibitor for treating adult and pediatric patients 12 years and older with Grade 2 astrocytoma or oligodendroglioma (brain tumors) with a susceptible IDH1 or IDH2 mutation, following surgery including biopsy, sub-total resection, or gross total resection.
Approval was based on data from the INDIGO (NCT04164901) placebo-controlled trial, an FDA release says. “The major efficacy outcome measure was progression-free survival (PFS) using a blinded independent review committee per modified Response Assessment in Neuro-Oncology for Low Grade Glioma (RANO-LGG) criteria,” it says. “An additional efficacy outcome measure was time to next intervention. The hazard ratio for PFS was 0.39 (95% CI: 0.27, 0.56), p-value <0.0001. The median time to next intervention was not reached for the vorasidenib arm and was 17.8 months for the placebo arm (HR=0.26; 95% CI: [0.15, 0.43], p <0.0001).”
Regarding safety, the most common adverse reactions were fatigue, headache, Covid-19 infection, musculoskeletal pain, diarrhea, nausea, and seizure, the agency says. The most common Grade 3 or 4 laboratory abnormalities were increased alanine aminotransferase, increased aspartate aminotransferase, GGT increased, and decreased neutrophils, it adds.
